Cooling System - Description

3.7L/4.7L/5.7L ENGINES




Engine Cooling System 4.7L Engine
The 3.7L/4.7L engine cooling system consists of :

- LH Cylinder Head (1)
- Bleeder Port (2)
- Thermostat location (3)
- RH Cylinder Head (4)
- RH Bank Cyl. Block (5)
- LH Bank, Cylinder Block (6)
- Coolant Temp Sensor (7)
- From Heater Core (8)
- To Heater Core (9)

The cooling system regulates engine operating temperature. It allows the engine to reach normal operating temperature as quickly as possible. It also maintains normal operating temperature and prevents overheating.




5.7L Engine Coolant System Flow
- LH Cylinder Head (1)
- To Radiator (2)
- From Radiator (3)
- To RH Cylinder Head (4)

The cooling system provides a means of heating the passenger compartment and cooling the automatic transmission fluid (if equipped). The cooling system is pressurized and uses a centrifugal water pump to circulate coolant through the system. The coolant system utilizes an ambient pressure coolant recovery container.
